Title: Needling method and apparatus
IPC: D04H18/00
Filed: 1973-01-08
Abstract: 1358821 Needling machine; patterning fabrics OSKAR DILO KG 8 Jan 1973 [18 Jan 1972] 1039/73 Headings D1R and D1S A laminate having a pattern of pile containing areas may be formed by needling together non-woven webs 13, 13'. The needling apparatus comprises a continuously rotating elongated drum 2 defining, according to the fuller description given in United States Patent No. 3530557, 100 circumferential grooves separated by annular ribs 3. A needling unit 4 is located adjacent each web delivery belt 12'. Each unit 4 has a row of needles corresponding to each circumferential groove on drum 2 the needles being arranged in a patterned array. As the planar needle boards 5 are reciprocated by a crank drive needles 6 pass through the web(s) into the grooves. The arcuate shape of the drum causes the outside needles 6' in each row to penetrate the web(s) less deeply so that the loops 16 they produce are shorter than and thereby support loops 17 produced by central needles 6", thereby stabilising the web(s). The needled multilayer fabric 15 is drawn off the drum by rolls 14. The webs may vary in colour, fibre denier and weight per unit area. A pattern effect is produced by pneumatically or hydraulically operated piston and cylinder displacement means 11 which are automatically operated to intermittently move each needling device 4 into and out of contact with the web(s), thereby producing needled and non-needled portions of the surface. The The pattern is programmed by placing pins or cams (22, Figure 3, not shown) in an endless belt (21) driven in synchronism with rolls 14. Adjacent belt (21) are two levers (23). The first, operated by contact with a pin on one side of the belt closes a switch (24) which causes means 11 to move the needling device 4 out of contact with the web(s). The second lever operated by pins on the opposite side of belt (21) causes the needling device 4 to be brought into contact with the web(s). Each needling unit may be programmed independently.

Abstract: 200,709. Baron, H., (Signal Ges.). Jan. 16, 1922. Diaphragm and plate vibrators.-The conduct. ing plates of a condenser sound transmitter are connected with the vibrating parts of an acoustic oscillatory structure or may themselves form the vibrating parts of such a structure. In the example shown in Fig. 1, condenser plates 1, 2 separated by air dielectric are mounted on a resilient hollow ring 4, the whole forming an oscillatory structure. A rotary commutator 22 effects the periodic variation of the charges cn the plates by connecting them alternately to different poles of a source of potential with or without an intermediate earth connection. As a modification, the plates are connected alternately to a source of potential and to earth or to one another. Inductances 18 and resistances 20 modify the form of the curve of charge and discharge. In another form, Fig. 2, the plates 1, 2 are coupled with air chambers having openings 29, 30 of small cross-section, by which the amplitude of the vibrations is increased. In.this case the plates are excited by an oscillatory cir. cuit 31 containing an electric arc 32. Reference has been directed by the Comptroller to Specifications 125,122, 139,497 and 145,691.

Patent GB-210434-A (GB)
Title: Process for obtaining alkali sulphides and sulphydrates
IPC: C01B17/32
Filed: 1924-01-23
Abstract: Alkali sulphides are obtained by treating a solution of an alkali metal salt such as sodium nitrate, chlorate carbonate, or sulphate, with barium sulphide in an atmosphere of sulphuretted hydrogen admitted from an external source.  The product is cooled out of contact with air and the barium nitrate is separated from the sodium hydrosulphide by crystallization, after which the hydrosulphide is converted to sulphide.  The separation of the reaction products is facilitated by adding a small quantity of carbon disulphide.  The Specification as open to inspection under Sect. 91 (3) (a) includes the use of alkaline earth sulphides instead of barium sulphide, alkali silicate as the alkali salt, and other reducing agents such as hydrogen, carbon monoxide, and saturated or unsaturated hydrocarbons instead of sulphuretted hydrogen to supply a reducing atmosphere.  A modification is described in which the reaction is effected in the dry way, sodium metasilicate, barium or calcium sulphide, and a small quantity of charcoal to provide the reducing atmosphere, being heated to 350-1500 DEG  C. at a pressure of 25 cms. of water.  This subject-matter does not appear in the Specification as accepted.

Title: Improved apparatus for sorting ferromagnetic articles according to their mechanical hardness
IPC: B07C5/08
Filed: 1938-01-20
Abstract: 509,780. Magnetic tests and separators. ARMOUR, A. M., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Jan. 20, 1938, No. 1947. [Class 37] [Also in Group II] For sorting similar ferromagnetic articles according to their mechanical hardness, the articles are first magnetised, then transferred to a position where they are subjected to a steady magnetic field, and sorted in accordance with their relative displacement or tendency thereto due to the interaction of the magnetic field and the remanent magnetism in the articles. Fig. 1 shows a drill 9 which is pushed through a non- magnetic tube 1 by a ram rod 8 to a position where it is magnetised by an electromagnet 4, and then to position 9a where it rests on an inclined platform 2. A permanent magnet 6 is then slid by means of a carrier 7 to within a predetermined distance of the platform and repels the drill 9 up the inclined platform 2, the displacement of the drill varying according to its residual magnetism which depends on its hardness. Drills of the required degree of hardness are arranged to be repelled over the upper edge of the platform from where they fall into a hopper 10 and pass therefrom though a demagnetising coil. Softer drills repelled only to position 9c, for example, roll back to position 9a after removal of the magnet 6 and may be then moved by hand or the ram rod 8 to another hopper..In a modification where the articles are each caused to move the same distance up an inclined plane the gradient thereof in each case serves for sorting. In another arrangement, the articles are fed on to a horizontal platform adjacent to an attracting magnet and the platform afterwards tilted so that softer articles roll away from the magnet and harder articles are retained in position. The platform may be corrugated to reduce friction. Non-rollable articles to be sorted may be loaded on to a non- magnetic rolling or tilting trolley moving over the sorting platform or may be inserted into a light non-magnetic tube, or the platform itself may have rollers over which the articles may roll. Alternatively, non-rollable articles may be loaded on to a platform which tilts under the repulsive action of the field on an article and is biased so as to tilt only if an article thereon is repelled a predetermined distance when the article slides off the platform into a container. In all cases the articles finally pass through a demagnetising device.
